The squirrel was probably my favorite once it got bigger but when I decided to make this a reef, the GSP and squirrel had to go. If it were me I’d keep what you have and do a wrasse and a snow flake eel. Snowflakes are really fun to feed and become very personable over time. I’d stay away from ribbon eels, they can very finicky and often starve. Any of the needle nose puffers would be very interesting as well. Don’t get big and are pretty much peaceful
